IMPRVED DIES FOR MAKING PLIERS.

TO ALL WI-IOM IT MAY CONCERN: s Beit known that I, SOLOMONH. WOOD, of East Berlin, county of Hartford, and State of Connecticut, have invented certain'new and useful Improvements in the Manufacture of Pliers, vand other like tools; and to enable others-skilled in the art to practise the same, I will proceed to describe byreferring to the drawings, in whichthe same letters indicate like parts in each of the figures. I l p The nature of this invention consists in constructing a pair of swage-des (upper and lower dies) for each half, consisting of the handle, joint, and jaw. One set ot' these dies is constructed to receive the metal, and form the jaws, joint, and handle edgewise. vOne set "of these dies is constructed to receive the metal, and form thejaws, joint, and handlesdewise. i

The object of this invention is tO facilitate and cheapen the manufacture, and render the work less irksome, and'more agreeable and pleasant for the workman, and produce greater uniformity of shape and style. In the accompanying drawingsi Figures l and 2 are side and edge views of one-half of a pair of pliers formed by the dies, as seen in figs, 5 and 6.

Figures and 4 are side and edge views of the other half ofv a. pair of pliers formed by the dies, as Seen in gs. 7 and 8. l

Figure 5 shows the form of the face Vof the dies employed for forming one part of the pliers.

Figure 6 shows the two dies, tig.A 5, closed together, with one portion of a h'andl'eas formed between them.

Figure 7 shows the face of the dies employed in forming thel'other part of the pliers.

Figure 8 shows the two dies, tig. ,7,- closed together in forming the other part ot' the pliers.

Fig. 2 shows the shape of the depression formed in each halt` of one pair of dies.

In fig. 3, a d show the lines (which intersect at e)lof the face of the dies in which tig. 4 s'fOrmed.

e is depressed or formed in one part of the die. z'i's depressedor worked out of the'other part .of the die, so that when asuitahle-sized'piece ofmetal is heated to a proper heat, and vplaced between the dies, (when they are arranged in a drop or press in the common-way of securing dies,) and power is applied thereto in the usual way, the shapes, as shown in iigs. I, 2, 3, `and 4, will be produced. 'l A slight, thin scale of metal, o, willremain, which will be readily removed by a punch and die inthe common way of punching netal. After'this the'slitted or female portion of the pliers, fig. 4, is heated and expanded, so as to receive the joint. portion o"of fig. 2. Thenv the i'lush metal is hammered or compressed to llthe depression o inl 2. Then a hole 'is drilled through the joint portion, and a fulcrum-pin inserted, when n. finish is produced much in the usual way.V

Thus I am enabled to produce pliers of a superior quality at less than' present importing prices, the labor is rendered pleasant and agreeable, and also to produce a valuable acquisition to home trade and manufacture.

I believe I have thus shown the nature and process of this,my improvement in the manufacture of pliers and other such like tools. I

i What I claim, therefore, and desire to secure by Letters Patent,tis-

The dies represented iu figs. 5 and 7, constructed and used inthe manner and for the purpose substantially as set forth.
